I think an experiment is necessary.

One issue that hasn't been pointed out yet is that "for every action, there is an equal and opposite reaction". Thus, in the event of a free-falling elevator, even if you could jump at the precise moment, the fact that you are jumping would cause the elevator to fall more quickly. So, if you force the elevator downward, then assuming that you could jump forcefully enough so that your motion in relation to the ground were stopped (which is highly unlikely), the TOP of the elevator would be coming at you at INCREASED speed, and that impact alone would likely be sufficient to kill you.

I guess it's a good thing that elevators are designed with safety mechanisms in place to prevent them from free-falling in the event of a mechanical failure!

I hope this helps!

If you were in an elevator that was free-falling then, the only way that you could save yourself would be:

1. To vertically jump with a certain amount of speed. That speed would have to equal the exact same speed as the elevator.

2. The jump would have to occur at the exact moment of impact

Unfortunately, human beings simply cannot jump with that amount of speed! Generating such force or thrust is physically impossible!

Even if such a force could be generated by humans, human beings typically lack the ability to pull off such precise timing under stressful conditions.

Unless you can jump up with an acceleration of 9.8 m/s2, gravity will affect you. You have to jump up as fast as the elevator is falling down-which can be really fast depending on how high the elevator is. You will most likely be injured.

there is no way that could happen because when your falling the elevator is not the only one plunging by the effect of gravity but also you too with the elevator will hender the same pull which will take great power to overcome it

I have read that you would not be saved by jumping at the last moment because you would still come to earth at that speed when you landed, or something like that.

Only if the elevator fell like 3 feet.

I saw this on Myth Busters. Long story short, jumping isn't going to help you.

if you were in an airplane descending very fast would you be able to jump at the last moment

NO ! (crazy questions)

What i only know is you must jump as fast as you could

I believe gravity would effect you!
